Answer:B). Cell membranes are composed of a lipid bilayer.
Explanation: A membrane is a lipid bilayer that surrounds the cell. Lipids have two parts: the fatty acid chain (the tail) and the phosphate group (the head).
The phosphate head groups are polar, face outward and interact with the outside environment of the cell. The fatty acid chain is hydrophobic and nonpolar, face each other in the bilayer thus forming a hydrophobic fluid interior.
The hydrophobic nature of the bilayer interior makes the membrane to permit only nonpolar and hydrophobic molecules to pass through the cell membrane. This is the reason the membrane allows only molecules that dissolve in the lipid bilayer to pass through to enter or leave the cell.
Answer:
Dark matter does not emit electromagnetic radiation.
Explanation:
Dark matter comparative to dark energy, has various differences. You could say that dark energy is put into action on a larger scale than dark matter, which is also why dark energy makes up 74 percent of the universe. Thus, dark matter ≠ dark energy.
Scientists have a lot to learn about dark matter, so we can't claim that this subject has been well understood about scientists. In fact, it is one of the least understood parts of the universe!
_______________________________________________________
Now dark matter can be defined as particles that do not absorb, reflect, or emit light. Thus, it can't be observed by electromagnetic radiation - nor shifts in red and blue light. At the same time it does not emit electromagnetic radiation.
This observation supports the theory of continental drift, and supports the theory of supercontinents.
